BOLSTER- -GUIDE PLATE FOR RAILWAY-CAR TRUCKS.

Application filed June 6, 1913. Serial No. 772,021.

To all whom it may concern:

@Bel it known that I, ALFRED CoroNY, a

citizen of the Austro-Hungarian Empire, residing at Verdun, bee andDominion of Canada, have invented (a certain new and useful Improvementin Bolster-Guide Plates for Railway-Car Trucks, of which the followingis a full,

clear, concise, and exact description, refer- -'10 encebeing hadto'theaccompanying drawings, forming a part of this specification.

My invention "relates to bolster guide 7 plates for railway car trucks.

- In usual construction of trucks for railmore particularly freightcars, the side truck frames are provided intermediate -'their ends withupright truck columns, generally in vertical arrangement and spacedapart, between which columns are arranged bolster guide plates seatedupon the truck springs, the bolster guide plates being in slidingengagement with the said columns and bearing theends of the truckqbolster. I-Ieretofore thebearing surfaces of the bolster guide platesat the point of their engagement with the truck columns have beensubstantially kept parallel to the adjacent, faces ofthe truck column,and as a resultjthereof when one set of wheels of a truck have beenderailed Without derailingtheother-set or sets of wheels the bolster,guide plates have bound between the truck-columns, thus tending tospread the truck columns and seriously damaging the t-ruckf It isnecessary in car construction thatfthere should be only a slightclearance, silbstantially not more than one-eighth of aninch,-betweenthe bolster guide plates and the truck column so that blows caused byhuffing shocks will be transmitted from the truck bolster to the truckframe with a minimum ofmovement of the truck holster. I w

he object of my invention-is to provide for. this minimum clearancebetween the truck bolster and truck frame at their pointsof-interengagement, and at the same time provide bolster guide plateswhich will permit the derailment of one. setof wheels of a truckwithoutbinding the truck bolster between the truck columns.

In the drawings'forming a partof this specification Figure 1 is a sideelevation of a truch frame with the bolster and bolster guide plates inposition therein, part of the truck frame being broken away, the bolsterSpecification of Letters Patent.

and bolster plates being partly in cross section on line l1 of Fig. 2.Fig. 2 is a top plan view about tl1e meeting point of. the end of thebolster and one of the truck side frames partly in horizontal section online 22 of Fig. 1. Fig. 3 is a perspective View of one of the bolsterguide plates.

In the drawings the numeral 4' represents a truck side frame, 5, 5 carwheels, the axles 6, 6 of which are suitably 'journaled to the truckframe. Intermediate its ends the truck side frame is provided with theopening 7, the sides of which are formed by the upright truck columns 8,8 within which opening are disposed the truck springs 9, 9, the truckbolster 10 and a pair of bolster guide plates 11, 11. The truck springsare seated at their lower ends againsttlie truck side frame, and attheir upper ends against the spring cap 12. The bolster guide plates arepreferably two in number for each side frame, each of said bolster guideplates comprising an upright .member 13 engaging one side of the truckbolster 10"at its inner face 14:, and having the curved outer or bearingface 15 adapted-to engage against the adjacent truck'column 8. r

The upright member 13 is provided at either endwith an outwardly turnedflange 16,-

the said flanges being adapted to engage the sides of the adjacent truckcolumn. In

preferable construction each of said flanges.

is provided along its outer edge with reinforcing flanges 17. Inpreferable construction the upright member 13 is provided at its loweredge with an angular flange 18 adapted to engage between the spring cap12 and the truck bolster 10, the said flange being provided with aplurality of upwardly extended lugs 19 adapted to engage withinperforations 20 in the lower face of'the truck bolster 10 to secure thebolster guide plate to the truck bolster. One of these bolster guideplates is arranged at each side of the truck bolster between thetruck-columns of each side truck frame.

It will be apparent that in the event of derailment of one set ofwheels, causing the truck frame to be lowered at one end and aconsequent change in the relative positions of the truck frame and carbody, that the truck bolst rs bearing .the weight of the car body willend to turn within the opening 7 of the truck'side frame, and that byreason of the; curved bearing face 15 with which each of the bolsterguide plates is provided there will be no binding of the plates andtruck bolster between the truck column;

It is preferable that the curve of the bearing face of each ofthebolster guide plates be of suitable radius to provide a umform.

bolster being provided with guide --plates adapted to engage saidcolumns, each of said guide plates having'a curved friction face.

2. In a railway car, in combination, a truck side frame having truckcolumns, a truck bolster disposed between said columns and bolster guideplates connected to the truck bolster, the said guide plates havingoutward curved bearing faces to engage the inner faces of the column,and flanges at of said column. 8. Ina railway car, in combination, aside truck frame, truck columns therein, truck springs and truck bolsterbetween said columns, the truck bolster being provided at eithersidewith bolster guide plates, each of said guide plateshaving an outwardcurved friction face.
